product description


The filaments or short fibers are laid into a net shape through different equipments and processes, and then different fibers are intertwined by a needle punching process, and the fibers are entangled and fixed to make the fabric normalized, so that the fabric is soft, full, thick and stiff. In order to achieve different thickness to meet the requirements of use, according to the length of the wire is divided into filament non-woven geotextile or short-filament non-woven geotextile.


The tensile strength of the filament is higher than that of the short filament. Because of the softness of the fiber, it has a certain tear resistance and has good filtration, water filtration and reinforcement. The main material is polyester fiber, which has superior water permeability, filterability, durability and deformation adaptability, and has good flat drainage capacity.






It is environmentally friendly building material without chemical additives and without heat treatment.


Has good mechanical properties, good water permeability, and can resist corrosion and anti-aging;


It has strong anti-buried and anti-corrosion properties and has a fluffy structure with good drainage performance.


Has a good coefficient of friction and tensile strength, with geo-reinforced properties;


With isolation, filtration, drainage, protection, stability, strengthening and other functions;


It can adapt to the uneven base layer, can resist the damage of construction external force, and has small creep;


Good overall continuity, light weight and convenient construction; it is a permeable material, so it has a good anti-filtering function and strong puncture resistance, so it has



Scope of application


Used as a reinforcement in the backfill of the retaining wall or as a panel for anchoring the retaining wall. Construct a wrapped retaining wall or abutment.


Reinforce the flexible pavement, repair the cracks on the road, and prevent the pavement from reflecting cracks.


Increase the stability of gravel slopes and reinforced soil to prevent soil erosion and freezing damage of soil during low temperature.


The isolation layer between the roadway and the roadbed, or the isolation layer between the roadbed and the soft foundation.


Isolation between artificial fill, rockfill or material field and foundation, and isolation between different frozen soil layers. Filtration and reinforcement.


The filter layer of the initial upstream dam surface of the ash dam or tailings dam, and the filter layer of the drainage system in the backfill of the retaining wall.


Drain the dark pipe around or the gravel drains the filter around the dark ditch.


The filter layer of a water well, a relief well or a diagonal pressure pipe in a water conservancy project.


Separation of geotextiles between the road, airport, railroad turnouts and artificial rockfills


The earth dam is drained vertically or horizontally, and is buried in the soil to dissipate the water pressure in the gap.


Drainage behind the anti-seepage geomembrane in the earth dam or earth embankment or in the lower part of the concrete facing.


Exclude water seepage around the tunnel, reduce the external water pressure on the lining and seepage around the buildings.


Manually fill the ground-based drainage of the sports ground.


Roads (including temporary roads), railways, embankments, earth-rock dams, airports, sports fields, etc. are used to strengthen weak foundations.
